A blog entry by Jure Repinc tells us about some of the new features in KDE 3.5 which according to this schedule isn't quite finished yet. Amongs other things, there will be a Storage Media Notification dialog and some more eye candy in Kicker.

But it still exludes the majority of Linux desktops and any ISV wanting to develop applications for it and releying on the LSB.

Only if the ISV wants to close the source. Source that would include TrollTech copyright code. Source that may also contain non-TrollTech copyright code.

TrollTech has an OPTION to ALLOW you to close the source by paying a licence fee. You may not have that OPTION if you use other open source not copyrighted by TrollTech.

If you distribute binaries based on open source code, you are responsible to provide the source if asked by the person or company that requests that source. Modifications are not necessary for most licences; it kicks in at the time of distribution.
